HOSE-COUPLING.

Application filed June 11,

T 0 all whom it may concern:

Be it known that i, ALEXis ALEXANDER Mnvonsxv, a subject of the Czar'of Russia, residing at VVilkmsburg, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements in Hose-Couplil'igs, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in hose couplings, and the inventlon'has for its object the provision of positive and reliable means for retaining the end of a hose upon a pipe, whether thesame be carried by a fire plug, hydrant or fire engine, etc.

. Another object of my invention is to provide a novel lock for preventing the hose coupling from being accidentally disconnected, as might occur if the hose were twisted ham ed exterior screw threads 2 and grovide the pipe member with a peripheral ployed for rotating the collar "largenient 10 is and moved;

"With the above and other objects in view, which will more readily appear as the inven tion is better understood, the same consists in the novel construction, combination and arrangement of parts to be presently .described and then specifically pointed out in the a pended claims.

Re erring to the drawing, Figure 1 is a sectional view of a hose coupling. Fig. 2 is an elevation of a collar forming part of the coupling. Fig. 3 is a cross sectional view of a pipe constituting one of the members of the couplin and Big. 4 is a perspective view of a loc "ng arm used in connection with the coupling.

'In the accompanying drawings 1 designates the pipe member of the hose coupling, the pipe member being providedwith ri ht wit 1 a tapering end 3. Adjacent to the threads, I

ange forming an annular socket in i the, socket 5 is, secured a resilient arm 6, and

ad'acent to the free end of said arm- I provide an extension 7, protruding into an openin r 8 formed in the flangc' i.

Threaded upon the incinberl is a collar 9 having a hexagon shaped cJ-largement 10, to accommodate a wrench (not shown) eniupon the pipe hiemberl. The' collar at one side of the enrovided with Specification of Letters Patent.

l screw threads 11, while the opposite side is f provided with-ratchet teeth 12. The flared l end 14 of a section of hose 15 is adapted to fit over the tapering end 3 of a pipe member 1'. Fitting upon the tapering end 14 of the hose is a sleeve 16 having interior left handed I screw threads 17 ada ted to screw u on the threads 11 of the col '1' 9. After t 1e hose 1 has beenplaced upon the tapering end of the 'pipe member, the sleeve 16 is rotated upon ;the collar to bind the hose upon the pipe member.

which draws inwardly upon the sleeve 16, further clamping the hose upon the pipe member.

In order that the ratchet end of the collar 9 can enter the socket 5, I have slightly beveled the ratchet teeth 12, as at 18, whereby the resilient arm (5 will be elevated and permit the ratchet end of the collar to seat in the socket 5. The resilient arm 6 is adapted to hold the collar 9 in a fixed position, until it is desired to disconnect the coupling, at which time the resilient arm is removed from engagement with the ratchet end of the collar. This is accomplished by inserting the finger in the opening 8 of the flange 4 and moving the extension 7 outwardly. The collar 9 can then be rotated to loosen the sleeve 16 and permit of the hose being removed from the end of the pipe memberv It will be ap arent from the foregoing description that have devised a pipe member, sleeve and collar having right and left hand ed screw threads, the last two mentioned elements being rotated in opposite directions to bind the end of a hose upon the pipe member. llhe collar and. sleeve of my The collar 10 is now rotated,
